ℹ️

These are 2D engineering drawings derived from the 3D CAD geometry. Verify critical dimensions against the source model before manufacturing.

🤖

Views, section cuts, and detail areas were selected by AI based on analysis of 6 rendered views of the 3D model.

AI Drawing Analysis

What the AI Decided & Why

The cards below explain how the generated drawing outputs and assets connect to the final technical sheets.

Assembly - Front View

Assembly - Front View

Orthographic

Shows the main external profile, the eccentric offset of the rotor’s centerline, and the depth of the internal cavity; essential for understanding the rotor’s interaction with the housing.

Assembly - Top View

Assembly - Top View

Orthographic

Reveals the triangular outer shape, the three mounting bolt holes at the vertices, and the concentric internal bore pattern; critical for locating the rotor in the housing and for assembly alignment.

Assembly - Left View

Assembly - Left View

Orthographic

Shows the side profile of the cavity and the thickness of the rotor’s side walls; useful for verifying wall thickness and clearance with the housing.

Section A-A

Section A-A

Orthographic

Reveals the internal epitrochoid cavity depth, the rotor’s wall thickness, and the relationship between the outer triangular face and the inner bore; essential for machining and inspection.

A — Asection_a · Section5
sheet_num: 5 · edges: 16

Reveals the internal epitrochoid cavity depth, the rotor’s wall thickness, and the relationship between the outer triangular face and the inner bore; essential for machining and inspection.

  • 16 resolved edges in sheet geometry
  • See technical_drawing_simple.pdf, sheet_N.pdf, and svg/ for full graphical context
  • Verify critical dimensions against the source CAD before manufacturing
Detail Cdetail_c · base_view: Front
anchor: (0, 0, 0) · radius: 5

Magnifies the fillet at the inner corner of the cavity to ensure proper stress relief and to verify the radius meets Wankel engine design standards.

  • Detail-view anchor selected by the AI planning stage
  • Use with sheet PDF/SVG for local feature inspection
  • Validate critical dimensions against source CAD before release

How these drawings were generated

These drawings were generated from the source 3D CAD geometry. The system analysed the model, selected relevant views, planned section cuts and generated drawing sheets in PDF, SVG and DXF formats.

These are 2D engineering drawings, not 3D files. Dimensions are extracted from the 3D geometry and should be verified against the source model before use in manufacturing.
